So no one would ever choose option 3, and no one would choose option 1, unless the installation was so small that the capital cost of the dual-channel meter would never be recovered. If it were truly the customer's choice, this would not be an issue, because the customer should always prefer #2 to #3. So what does TVA do (if anything) to get customers to pick #3, or force them into it? Also note that net metering is not an option. #2 uses a dual-channel meter to track outgoing power separately from incoming power. Net metering is not necessarily the optimal metering solution, either, but TVA doesn't even offer it.
